1914. Serial No. 832,907. A

1b all whom it may concern Be it known that I, NELSON M. BAKER, a

- citizen of the United States, residing at southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Spectacles, of which the following is a specifica- Klinger pieces for manipulating them, and

has for its object; to provide an improved bearing for the finger piece which will be secure and which will not readily wear out pressure 18 exerted on the nose of the wearer thrcu h continued use.'

' provision in a mounting of the character rther object of my' invention is the mentioned, in which the support is provided with a pivot to one side thereof, on which the lever are mounted, of means interposed between the head of the pivot and the lever,

for steadyingthe lever and preventing wabbling thereof.

More specifically stated, my invention re sides in plaoing upon the pivot a tubular .member-actingoas a distance piece between I within the scope of the appended claims one side of the lever and the head of the pivot, whereby the sleeve limits axial movement of the lever on the pivot.

Other objects and advantages of my improvements should be readily apparent by reference to the following description taken in connection with the accompanying drawmake any modifications in the specific detalls of constructlon shown and described without departing from or exceeding the spirit of my invention. 1 v r This specificetionis a division of a application tiled by me. ()ctober 10, 1908.,

- 'Serial No. 457,119.

Figure I is a face view of a pair ofveyeglasses, my invention applied tlu-nretoL Fig. II is a plan view thereof, Fig. III isan enlarged detail view with the partsin section.

' (0;) represents the nose bridge, to each end of which are secured the lens clamps (b) be prior tween which are fastened the lenses (0). N ose. clamps (d) serve to maintain the glasses in position on the face and are provided with lever arms (6) which terminate 1n operating finger pieces (f). Screws (9') entend into the nose piece (a) and serve as pivots by which the lever arms (6) and nose clamps (03) may be swung, the lever arms being. preferably perforated to receive the screws. A spring (h) surrounds each of said screws (9) with its one end abutting against the lens clamp (b) and its other end in engagement with the nose clamp (03). The tendency of this spring is to press the nose clamps (d) toward each other so that a for maintaining the glasses in position. To limit axial movement of the arm ((2) on the pivot Iprovide a sleeve having a shoulder or flange (2"), said sleeve surrounding the screw (g) and the shoulder portion (i) being disposed above the arm.

In Fig. III, I have shown the sleeve as fitting around the pivot throughout its whole length, the actuating spring being coiled around the sleeve and thus separated from the pivot screw by the sleeve.

To secure most efficient results I have shown the sleeve as extending downward be- .low the shoulder portion (11) through the lever into engagement with the support, thus. serving as a spacing member to prevent pinching of the .lcver'between the shoulder of the sleeve and the support, but it will be understood that 'the' sleeve will operate equally satisfactory so faras prevention of axial movement on the pivot is concerned should itterminate at the lever, but more care would be necessitated in assembling of the parts. I

I 'claim':

1. The combination with a support, of a pivot carried thereby having a head on its outer end, alever on the pivot, a sleeve on the pivot beneath the head of the pivot confining the lever axially on the pivot, and an actuating spring for the lever encircling the sleeve and disposed in the space between the lever andthe head of the pivot.

2. The combination with a support, of a pivot carried thereby, a lever pivot-ally mounted on the support, a sleeve on the pivot having a shoulder resting on the opposite side of the lever from the support and having a portion extending between the lever and the head of the pivot, and an actuatil lg spring mounted on the sleeve exterior to sand shoulder.

In testimony whereof I afiix my signetm'e in presence of two witnesses. 1
